We can use the cournot model to derive an equilibrium industry structure. for this purpose, we will define an equilibrium as that structure in which no firm has an incentive to leave or enter the industry. if a firm leaves the industry, it enters an alternative competitive market in which case it earns zero (economic) profit. if an additional firm enters the industry when there are already n firms in it, the new firm's profit is determined by the cournot equilibrium with n + 1 firms. for this problem, assume that each firm has the cost function: c(q) = 256 +20_q. assume further that market demand is described by: p = 100 - q. a. find the long-run equilibrium number of firms in this industry. b. what industry output, price, and firm profit levels will characterize the long-run equilibrium?

Juniper company uses a perpetual inventory system and the gross method of accounting for purchases. the company purchased $9,750 of merchandise on august 7 with terms 1/10, n/30. on august 11, it returned $1,500 worth of merchandise. on august 26, it paid the full amount due. the correct journal entry to record the merchandise return on august 11 is:

Paar corporation bought 100 percent of kimmel, inc., on january 1, 2012. on that date, paar’s equipment (10-year life) has a book value of $420,000 but a fair value of $520,000. kimmel has equipment (10-year life) with a book value of $272,000 but a fair value of $400,000. paar uses the equity method to record its investment in kimmel. on december 31, 2014, paar has equipment with a book value of $294,000 but a fair value of $445,200. kimmel has equipment with a book value of $190,400 but a fair value of $357,000. the consolidated balance for the equipment account as of december 31, 2014 is $574,000. what would be the impact on consolidated balance for the equipment account as of december 31, 2014 if the parent had applied the initial value method rather than the equity method? the balance in the consolidated equipment account cannot be determined for the initial value method using the information given. the consolidated equipment account would have a higher reported balance. the consolidated equipment account would have a lower reported balance. no effect: the method the parent uses is for internal reporting purposes only and has no impact on consolidated totals.
